Question
A kite is in the shape of a square with a diagonal 24cm,
attached to an equilateral triangle of the base 6cm. How much paper has been used to make it?Solution
Area of the square = 1/2 × (Diagonal)^2 = 1/2 ×(24)^2 = 1/2 × 24 × 24 = 288 cm² Area of equilateral triangle = √3/4 × (side)^2 = √3/4 × 6 × 6 = 9√3 cm² Total area = 288 + 9√3 = 9(32 +√3)cm²
(22 × 52 ) + 4 × 6 = ? - √324
What should come in place of (?) question mark in the given expression.
 (25% of 320) + (3/8 of 400) − 30 = ?
(5832)1/3  × 10.11 × 11.97 ÷ 16.32 = ? + 45.022
82% of 400 + √(?) = 130% of 600 - 85% of 400
If (x + 1/x) = 5, then value of x3 + 1/x3 is:
Simplify: (1 ÷ 0.08)
What should come in place of (?) question mark in the given expression.
{ (144 ÷ 12) × 5 } − (18 ÷ 3) = ?
Simplify the following expressions and choose the correct option.
(3/4 of 256) + (2/5 of 150) - (72 ÷ 7)
464 + 181 +? = (154 × 25) - (15) 2 Â
15% of 1800 + 22 = ?Â
